[Citrate concentration in samples for physiological coagulation investigations (author's transl)].

Citrate determination in coagulation blood samples sometimes end considerable deviations from the prescribed end concentration. Only a part of these samples can be recognized in the laboratory by simple inspection, in the undiscovered cases faulty results must be reckoned with. The citrate end concentration is more reproducible under routine conditions when a special sampling apparatus (Citrate-Monocuvette) is used.
